Abstract (en)

[origin: EP3809064A1] In a refrigeration cycle apparatus (100), refrigerant circulates through a compressor (1), a first heat exchanger (2), a first expansion valve (3), a refrigerant container (4), a second expansion valve (5) and a second heat exchanger (6) in this order. The refrigeration cycle apparatus (100) includes: a third expansion valve (8); and a specific flow path (71). The specific flow path (71) allows the third expansion valve (8) to communicate with the refrigerant container (4). The third expansion valve (8) communicates with a suction port of the compressor (1) through the refrigerant container (4). An amount per unit time of the refrigerant passing through the specific flow path (71) when a specific condition is satisfied is larger than the amount per unit time of the refrigerant passing through the specific flow path (71) when the specific condition is not satisfied. The specific condition is a condition that an amount of the refrigerant in the refrigerant container (4) is smaller than a reference amount.
